    Like I said, LaserBoy is the same as LFI Player for the Default palette. Anarchy is different. So I must not have gotten the table from Anarchy. Although, it is right there in a plain text file. So it would have been super easy. The only way I see to get the palette table from LFI Player is to look at the source code. When did it go into open source? I don't think it was in 2003 when I started writing ILDA file code. I never even downloaded anything by LFI until yesterday!

    BTW, at the same time in 2003 I got the color tables for X29 and the ILDA Standard palette which has all 256 values defined and starts with index zero as black.

    Anyway....

    I did a bit more testing. I made a frame with lines of palette indexes 54, 55, 56, 57, 58, 59, 60.
    I used the same technique of capturing the screen to Paint Shop Pro and checked the RGB values of each line.
    For this group of palette indexes, LaserBoy and LFI Player are exactly the same!
    Looking into it a bit further, it seems like the difference between (LB + LFI) and Anarchy is at index 46. Anarchy has a value in that position of (192, 0, 255) and all of the indexes that follow it are pushed up one place from there to the end of the palette (compared to LB & LFI).

    So, white is 55 and 57 in both LaserBoy and LFI.
    White is 56 and 58 in Anarchy.
    White is only 56 in the 2014 ILDA Spec.

    So I am really confused now about where I got the RGB table for the Default palette! I really don't remember. Did I get it from the same source as LFI Player or did LFI Player get it from LaserBoy?

    BTW, neither Anarchy or LFI Player seem to be able to read an ILDA format 2 color palette. I put an alternate palette in the middle of in.ild and both apps fail to read the file entirely.

    UPDATE: I just downloaded the source code for LFI Player and found the file where the included palettes are defined. It is dated 2005 in the header of the file. That was well before any public release of LaserBoy. I have no reason to believe that the palette definitions in this file have been altered since they were first written. So it's safe to say that LaserBoy got the same palette definition some time later. One difference is that the last unique value in the palette is repeated to the end of a full 256 values.
    Anarchy has the ability to save and load its own custom palettes and it works within the context of the program, but it's implementation of format 2 tables isn't quite right to the ILDA standard.

    To me it looks like you just skipped #46 in the Anarchy table so #63 was left over and you set it to black. When I made my ILD reader, I assumed Anarchy #58 was a typo, since white was already in #56 so I set green and blue in #58 to 192 to conform to the overall palette pattern. I also saw a blip at Anarchy #35 where red was 10 when it should be 0 to fit the overall pattern.
    Once these two blips are corrected, the only key difference between Anarchy and ILDA table is that Anarchy has a radical drop in green level starting at #32, the ILDA version is more consistent with the overall palette pattern- perhaps this is the P word tweak that Steve spoke of.

    OK, enough of the Scribes and Pharisees debates... Back to original topic-
    Jerilyng, were you able to get any ILD files from LaserBoy to load in your setup?
